Raspberry pi 4 / kodi

[sajuuk]

Hi all,

I'm trying to run kodi on the rpi4 but I'm a bit lost.
This a clean install from the provided arch image.

Firstly I installed the kodi-rbp4 package and enabled de kodi service to start kodi at launch. (I don't have any other graphical application)
But on launch Kodi gave me an error telling that the GUI couldn't be created.

I figured I was missing some video drivers or something like that.

After a bit of digging I found that I could enable the video driver by adding those lines to my config.txt.

$this->bbcode_second_pass_code('', '
gpu_mem=128
dtoverlay=vc4-kms-v3d
')

Now kodi boot but the screen itself is still black.
I checked on the two micro-hdmi and there is no output.
Also the rpi itself seems a bit sluggish (first connect in SSH is slow and some commands seems to take longer to run).

There are no errors in kodi.log only this at the end

Any idea what I'm doing wrong ?

Thanks

Sometimes I guess you only have to ask the question to find the answer by yourself...

So I had added the following line to my config.txt
$this->bbcode_second_pass_code('', 'dtoverlay=vc4-kms-v3d')

But I should have used
$this->bbcode_second_pass_code('', 'dtoverlay=vc4-fkms-v3d')
(notice the missing f which tell to use the fake driver)

No it works corretly !

Pacman tells you this when you install:
$this->bbcode_second_pass_code('', '[2019-08-02 19:33] [ALPM] installed kodi-rbp4 (18.3-2)

')

Thanks I missed that...

Is there some post install step/configuration to do afterwards ?
I think the playback is a little choppy on my rpi.

[graysky]

Just those modifications.

Ok thanks.
I had some thermal problem, with the case open and a heatsink on the cpu everything runs smoothly.
